Patent Application No. 110107519, filed on Mar. 3, 2021. The entire
content of the above identified application is incorporated herein
by reference.
[0002] Some references, which may include patents, patent
applications and various publications, may be cited and discussed
in the description of this disclosure. The citation and/or
discussion of such references is provided merely to clarify the
description of the present disclosure and is not an admission that
any such reference is "prior art" to the disclosure described

FIELD OF THE DISCLOSURE
[0003] The present disclosure relates to an electronic apparatus,
and more particularly to an outdoor electronic apparatus and a
sunshade thereof.
BACKGROUND OF THE DISCLOSURE
[0004] A conventional outdoor electronic apparatus often
experiences a rise in temperature due to exposure to sunlight.
Accordingly, for the conventional outdoor electronic apparatus, the
sunlight can be shielded by additionally assembling a sunshade onto
an electronic device of the conventional outdoor electronic
apparatus. However, the sunshade of the conventional outdoor
electronic apparatus often decreases a heat dissipation effect from
convection of the electronic device.
SUMMARY OF THE DISCLOSURE
[0005] In response to the above-referenced technical inadequacy,
the present disclosure provides an outdoor electronic apparatus and
a sunshade thereof to effectively improve on the issues associated
with conventional outdoor electronic apparatuses.
[0006] In one aspect, the present disclosure provides an outdoor
electronic apparatus, which includes a sunshade and an electronic
device that is assembled to the sunshade. The sunshade includes a
top shield and a plurality of shielding structures that are formed
on the top shield. The top shield has a plurality of top convection
holes each having a hole area, and at least part of the top
convection holes respectively correspond in position to the
shielding structures. An edge of any one of the shielding
structures and a hole edge of the corresponding top convection hole
jointly define a first interface region having an outflow area.
Moreover, a top portion of the electronic device and the top shield
have a heat dissipating space there-between that is in spatial
communication with the top convection holes. The sunshade and an
outer surface of the electronic device jointly define a second
interface region that is in spatial communication with the heat
dissipating space and that has an inflow area, and wherein the
inflow area is greater than or equal to at least 20% of a sum of
the outflow areas of the top shield.
[0007] In another aspect, the present disclosure provides an
outdoor electronic apparatus, which includes a sunshade and an
electronic device that is assembled to the sunshade. The sunshade
includes a top shield and a plurality of shielding structures that
are formed on the top shield. The top shield has a plurality of top
convection holes each having a hole area, and at least part of the
top convection holes respectively correspond in position to the
shielding structures. An edge of any one of the shielding
structures and a hole edge of the corresponding top convection hole
jointly define a first interface region having an outflow area. A
sum of the hole areas of the top convection holes is greater than
or equal to at least 20% of a sum of the outflow areas of the top
shield. Moreover, a top portion of the electronic device and the
top shield have a heat dissipating space there-between that is in
spatial communication with the top convection holes.
[0008] In yet another aspect, the present disclosure provides a
sunshade of an outdoor electronic apparatus. The sunshade includes
a top shield and at least one shielding structure. The top shield
has at least one top convection hole having a hole area. The at
least one shielding structure is formed on the top shield and
corresponds in position to the at least one top convection hole.
Moreover, an edge of the at least one shielding structure and a
hole edge of the at least one top convection hole jointly define a
first interface region having an outflow area. The hole area is
greater than or equal to at least 20% of the outflow area.
[0009] Therefore, the outdoor electronic apparatus of the present
disclosure allows airflow to flow smoothly therein by the
structural design of the sunshade or the structural cooperation of
the sunshade and the electronic device (e.g., the inflow area is
greater than or equal to at least 20% of the sum of the outflow
areas of the top shield).
[0010] Specifically, by the structural cooperation of the shielding
structures and the top convection holes in the sunshade of the
present disclosure (e.g., the sum of the hole areas of the top
convection holes is greater than or equal to at least 20% of the
sum of the outflow areas of the top shield; or, in any one of the
shielding structures and the corresponding top convection hole, the
hole area is greater than or equal to at least 20% of the outflow
area), any one of the shielding structures can be configured to
shield sunlight and to simultaneously avoid affecting the flow of
air passing through the corresponding top convection hole, so that
the outdoor electronic apparatus can have a better convection
effect.
[0011] Moreover, the shielding structures of the sunshade in the
present disclosure cover 1% to 100% of the sum of the hole areas of
the top convection holes along the vertical direction, so that the
shielding structures can be used to effectively shield sunlight for
the top convection holes.
[0012] These and other aspects of the present disclosure will
become apparent from the following description of the embodiment
taken in conjunction with the following drawings and their
captions, although variations and modifications therein may be
affected without departing from the spirit and scope of the novel
concepts of the disclosure.

First Embodiment
[0029] Referring to FIG. 1 to FIG. 7, a first embodiment of the
present disclosure provides an outdoor electronic apparatus 1000
that preferably excludes any indoor electronic apparatus. The
outdoor electronic apparatus 1000 includes a sunshade 100 and an
electronic device 200 that is assembled to the sunshade 100, but
the type of the electronic device 200 can be changed or adjusted
according to design requirements.
[0030] It should be noted that the sunshade 100 in the present
embodiment is described in cooperation with the electronic device
200, but the present disclosure is not limited thereto. For
example, in other embodiments of the present disclosure, the
sunshade 100 can be independently used (e.g., sold) or can be used
in cooperation with other devices. In the present embodiment, FIG.
1 and FIG. 2 show a specific structure of the outdoor electronic
apparatus 1000, and FIG. 3 to FIG. 7 show schematic structures of
the outdoor electronic apparatus 1000 for clearly describing most
structural features, but the present disclosure is not limited
thereto.
[0031] As shown in FIG. 3 to FIG. 5, the sunshade 100 in the
present embodiment is integrally formed as a single one-piece
structure, and the sunshade 100 includes a top shield 1, a
plurality of shielding structures 2 formed on the top shield 1, and
a lateral shield 3 that is connected to (or extends from) a
peripheral edge of the top shield 1. It should be noted that the
sunshade 100 in the present embodiment is provided by forming the
above elements, but in other embodiments of the present disclosure
not shown in the drawings, the sunshade 100 can be provided without
the lateral shield 3.
[0032] In the present embodiment, the top shield 1 is a flat board
and has a plurality of top convection holes 11 penetrating
there-through. Each of the top convection holes 11 has a hole area.
Specifically, the top convection holes 11 in the present embodiment
are substantially and uniformly distributed on the top shield 1 and
have a substantially same shape (e.g., an elongated shape), but the
present disclosure is not limited thereto. For example, in other
embodiments of the present disclosure not shown in the drawings,
the top convection holes 11 can be of different shapes; or, the top
shield 1 is not a flat board.
[0033] At least part of the top convection holes 11 respectively
correspond in position to the shielding structures 2, so that the
shielding structures 2 can cover 1% to 100% (e.g., 20% to 100%) of
a sum of the hole areas of the top convection holes 11 along a
vertical direction H. Accordingly, the shielding structures 2 can
be used to effectively shield sunlight for the top convection holes
11.
[0034] In the present embodiment, a quantity of the shielding
structures 2 is equal to (as shown in FIG. 3) or less than (as
shown in FIG. 1) a quantity of the top convection holes 11. In
other words, a few of the top convection holes 11 can be not
covered by the shielding structures 2, and the sum is obtained by
adding together the hole areas of all of the top convection holes
11.
[0035] Furthermore, in other embodiments of the present disclosure
not shown in the drawings, a quantity of the top convection hole 11
formed on the top shield 1 can be at least one, a quantity of the
shielding structure 2 formed on the top shield 1 can be at least
one, and the at least one shielding structure 2 corresponds in
position to the at least one top convection hole 11, so that the at
least one shielding structure 2 can cover 1% to 100% (e.g., 20% to
100%) of the hole area of the at least one top convection hole 11
along the vertical direction H.
[0036] Specifically, as shown in FIG. 3 to FIG. 5, the shielding
structures 2 in the present embodiment are formed on one side of
the top shield 1 (e.g., an upper side of the top shield 1) away
from the electronic device 200, but the positions of the shielding
structures 2 can be changed or adjusted according to design
requirements. For example, as shown in FIG. 6 and FIG. 7, at least
one of the shielding structures 2 can be located between the
electronic device 200 and the top shield 1; or, at least one of the
shielding structures 2 can be formed on one side of the top shield
1 away from the electronic device 200.
[0037] As shown in FIG. 3 to FIG. 5, any one of the shielding
structures 2 in the present embodiment extends from a hole edge of
the corresponding top convection hole 11, and an edge of any one of
the shielding structures 2 and the hole edge of the corresponding
top convection hole 11 jointly define a first interface region F1
(e.g., a U-shaped region surrounded by two-dot chain lines shown in
FIG. 3) having an outflow area, but the present disclosure is not
limited thereto. For example, in other embodiments of the present
disclosure not shown in the drawings, any one of the shielding
structures 2 can be connected to a portion of the top shield 1
arranged adjacent to the corresponding top convection hole 11.
[0038] Moreover, the shielding structures 2 in the present
embodiment have a substantially same structure (e.g., an L-shaped
structure), and any one of the shielding structures 2 includes a
supporting portion 21 that is connected to the top shield 1 and a
shielding portion 22 that is connected to the supporting portion
21. The shape of the shielding portion 22 of any one of the
shielding structures 2 is substantially identical to the shape of
the corresponding top convection hole 11, and the shielding
portions 22 of the shielding structures 2 respectively extend from
the supporting portions 21 along a same direction, but the present
disclosure is not limited thereto.
[0039] For example, in other embodiments of the present disclosure
not shown in the drawings, the shielding structures 2 can be of
different structures; or, the shape of any one of the shielding
portions 22 can be different from the shape of the corresponding
top convection hole 11; or, the shielding portions 22 of the
shielding structures 2 can respectively extend from the supporting
portions 21 along different directions.
[0040] As shown in FIG. 3 to FIG. 5, the lateral shield 3 in the
present embodiment is in a loop shape, and a top portion (e.g., a
heat sink) of the electronic device 200 is located in a space
surrounded by the top shield 1 and the lateral shield 3. The top
portion of the electronic device 200 and the top shield 1 have a
heat dissipating space S there-between that is in spatial
communication with the top convection holes 11, and the lateral
shield 3 surrounds an outside of the heat dissipating space S.
[0041] Specifically, the sunshade 100 and an outer surface of the
electronic device 200 jointly define a second interface region F2
(e.g., a loop-shaped region surrounded by two-dot chain lines shown
in FIG. 4) that is in spatial communication with the heat
dissipating space S and that has an inflow area. In the present
embodiment, the lateral shield 3 and the top portion of the
electronic device 200 have a loop-shaped space R there-between that
is in spatial communication with the heat dissipating space S.
Moreover, a cross section of the loop-shaped space R perpendicular
to the vertical direction H has an area that is equal to the inflow
area. In other words, the cross section of the loop-shaped space R
can be regarded as the second interface region F2.
[0042] The outdoor electronic apparatus 1000 in the present
embodiment enables airflow A to be received from the second
interface region F2, and enables the airflow A to be guided and
flow outside of the sunshade 100 by traveling along the heat
dissipating space S, the top convection holes 11, and the first
interface region F1, so that heat energy generated from the
electronic device 100 can be transmitted outside of the sunshade
100 by the airflow A, but the present disclosure is not limited
thereto.
[0043] It should be noted that, in order to allow the airflow A to
smoothly flow in the outdoor electronic apparatus 1000, the
connection relationship of the components of the outdoor electronic
apparatus 1000 preferably satisfies the following conditions, but
the present disclosure is not limited thereto. For example, in
other embodiments of the present disclosure not shown in the
drawings, the connection relationship of the components of the
outdoor electronic apparatus 1000 can satisfy at least one of the
following conditions.
[0044] In the present embodiment, the sum of the hole areas of the
top convection holes 11 is greater than or equal to at least 20%
(e.g., 30% to 150%) of a sum of the outflow areas of the top shield
1. In any one of the shielding structures 2 and the corresponding
top convection hole 11, the hole area is greater than or equal to
at least 20% (e.g., 30% to 150%) of the outflow area.
[0045] Accordingly, by the structural cooperation of the shielding
structures 2 and the top convection holes 11 in the sunshade 100 of
the present embodiment, any one of the shielding structures 2 can
be configured to shield sunlight and to simultaneously avoid
affecting the flow of air passing through the corresponding top
convection hole 11, so that the outdoor electronic apparatus 1000
can have a better convection effect.
[0046] Moreover, the sum of the hole areas of the top convection
holes 11 in the present embodiment is at least 20% (e.g., 30% to
150%) of the inflow area, and the inflow area in the present
embodiment is greater than or equal to at least 20% (e.g., 30% to
150%) of the sum of the outflow areas of the top shield 1.
[0047] In addition, as shown in FIG. 1 and FIG. 2, the top shield 1
has an assembling opening 12, the top convection holes 11 are
arranged to surround an outside of the assembling opening 12, and
the top portion of the electronic device 200 can be fixed to an
external object (not shown in the drawings) through the assembling
opening 12. An area of the assembling opening 12 is greater than
the hole area of any one of the top convection holes 11. In other
words, any opening formed in a shield and provided for assembling
is different from the top convection holes 11 of the present
embodiment.
[0048] Furthermore, the lateral shield 3 in the present embodiment
has a plurality of lateral convection holes 31 penetrating
there-through, and the lateral convection holes 31 are arranged to
surround an outside of the top convection holes 11. The sunshade
100 in the present embodiment does not have any shielding structure
2 corresponding in position to any one of the lateral convection
holes 31, thereby enabling the lateral convection holes 31 to
quickly dissipate heat energy, but the present disclosure is not
limited thereto. For example, in other embodiments of the present
disclosure not shown in the drawings, the lateral shield 3 can be
formed without any of the lateral convection holes 31; or, the
lateral shield 3 can include at least one shielding structure 2
corresponding in position to at least one of the lateral convection
holes 31.
Second Embodiment
[0049] Referring to FIG. 8 to FIG. 10, a second embodiment of the
present disclosure is similar to the first embodiment of the
present disclosure. For the sake of brevity, descriptions of the
same components in the first and second embodiments of the present
disclosure (e.g., the top shield 1, the shielding structures 2, and
the electronic device 200) will be omitted herein, and the
following description only discloses different features between the
first and second embodiments.
[0050] In the present embodiment, the lateral shield 3 is in a
C-shape and surrounds a part of the heat dissipating space S, so
that the lateral shield 3 and the top portion of the electronic
device 200 have a C-shaped space C there-between that is in spatial
communication with the heat dissipating space S. The lateral shield
3 does not cover a part of the heat dissipating space S along a
predetermined direction P perpendicular to the vertical direction
H, and does not cover a part of the electronic device 200 along the
predetermined direction P. In other words, the part of the heat
dissipating space S (or the part of the electronic device 200) not
covered by the lateral shield 3 corresponds in position to a notch
of the C-shaped space C.
[0051] Specifically, the C-shaped space C has a cross section
perpendicular to the vertical direction H, and the inflow area is
equal to a sum of an area of the cross section of the C-shaped
space C (e.g., an area of a region F21 surrounded by two-dot chain
lines shown in FIG. 9) and an area of a cross section of the heat
dissipating space S perpendicular to the predetermined direction P
(e.g., an area of a region F22 surrounded by two-dot chain lines
shown in FIG. 10). In other words, the second interface region in
the present embodiment includes the region F21 shown in FIG. 9 and
the region F22 shown in FIG. 10.
Third Embodiment
[0052] Referring to FIG. 11 to FIG. 13, a third embodiment of the
present disclosure is similar to the first embodiment of the
present disclosure. For the sake of brevity, descriptions of the
same components in the first and third embodiments of the present
disclosure (e.g., the top shield 1, the shielding structures 2, and
the electronic device 200) will be omitted herein, and the
following description only discloses different features between the
first and third embodiments.
[0053] In the present embodiment, the lateral shield 3 includes a
shielding segment 32 and an end segment 33. The shielding segment
32 in the present embodiment is in a C-shape and surrounds a part
of the heat dissipating space S, so that the lateral shield 3 and
the top portion of the electronic device 200 have a C-shaped space
C there-between that is in spatial communication with the heat
dissipating space S. The end segment 33 is connected to (or extends
from) the shielding segment 32 and is located in a notch of the
shielding segment 32, but the present disclosure is not limited
thereto. For example, in other embodiments of the present
disclosure not shown in the drawings, the shape of the shielding
segment 32 can be changed or adjusted according to design
requirements.
[0054] Moreover, the C-shaped space C has a cross section
perpendicular to the vertical direction H. The end segment 33 does
not cover a part of the heat dissipating space S along a
predetermined direction P perpendicular to the vertical direction
H. The part of the heat dissipating space S not covered by the end
segment 33 has a transverse section (e.g., a region F23-1
surrounded by two-dot chain lines shown in FIG. 13) perpendicular
to the predetermined direction P, and a region between the end
segment 33 and the heat dissipating space S has a longitudinal
section (e.g., a region F23-2 surrounded by two-dot chain lines
shown in FIG. 12) perpendicular to the vertical direction H.
[0055] Specifically, the inflow area is equal to a sum of an area
of the cross section (e.g., an area of a region F21 surrounded by
two-dot chain lines shown in FIG. 12) of the C-shaped space C and a
larger one of an area of the transverse section and an area of the
longitudinal section. In other words, the second interface region
in the present embodiment includes the region F21 shown in FIG. 12
and a larger one of the region F23-1 shown in FIG. 13 and the
region F23-2 shown in FIG. 12.
[0056] For example, the area of the transverse section (e.g., the
region F23-1) shown in FIG. 13 is less than the area of the
longitudinal section (e.g., the region F23-2) shown in FIG. 12, so
that the inflow area is equal to a sum of the area of the cross
section of the C-shaped space C and the area of the longitudinal
section, but the present disclosure is not limited thereto. In
other words, in other embodiments of the present disclosure not
shown in the drawings, the area of the transverse section can be
greater than the area of the longitudinal section, so that the
inflow area is equal to a sum of the area of the cross section of
the C-shaped space C and the area of the transverse section.
Beneficial Effects of the Embodiments
[0057] In conclusion, the outdoor electronic apparatus of the
present disclosure allows airflow to smoothly flow therein by the
structural design of the sunshade or the structural cooperation of
the sunshade and the electronic device (e.g., the inflow area is
greater than or equal to at least 20% of the sum of the outflow
areas of the top shield).
[0058] Specifically, by the structural cooperation of the shielding
structures and the top convection holes in the sunshade of the
present disclosure (e.g., the sum of the hole areas of the top
convection holes is greater than or equal to at least 20% of the
sum of the outflow areas of the top shield; or, in any one of the
shielding structures and the corresponding top convection hole, the
hole area is greater than or equal to at least 20% of the outflow
area), any one of the shielding structures can be configured to
shield sunlight and to simultaneously avoid affecting the flow of
air passing through the corresponding top convection hole, so that
the outdoor electronic apparatus can have a better convection
effect.
[0059] Moreover, the shielding structures of the sunshade in the
present disclosure cover 1% to 100% of the sum of the hole areas of
the top convection holes along the vertical direction, so that the
shielding structures can be used to effectively shield sunlight for
the top convection holes.
[0060] The foregoing description of the exemplary embodiments of
the disclosure has been presented only for the purposes of
illustration and description and is not intended to be exhaustive
or to limit the disclosure to the precise forms disclosed. Many
modifications and variations are possible in light of the above
teaching.
[0061] The embodiments were chosen and described in order to
explain the principles of the disclosure and their practical
application so as to enable others skilled in the art to utilize
the disclosure and various embodiments and with various
modifications as are suited to the particular use contemplated.
Alternative embodiments will become apparent to those skilled in
the art to which the present disclosure pertains without departing
from its spirit and scope.
